Quick Start

Create a PLC
// Issue a Cryptographic Liquidity Promise (PLC)
POST /api/v1/plcs

{
  "amount": 150.00,
  "currency": "BRL",
  "issuer_pubkey": "ed25519:abc123...",
  "expires_in": 86400
}

// Response
{
  "id": "plc_7f3a...",
  "status": "ISSUED",
  "commitment_hash": "sha256:e3b0c44...",
  "signature": "sig_ed25519:..."
}

Offline-First

PLCs can be created, transferred, and verified entirely offline using BLE, NFC, or QR codes. Settlement occurs when connectivity returns.

Cryptographically Secure

Ed25519 signatures, XChaCha20-Poly1305 encryption, SHA-256 commitments, and Argon2id key derivation protect every transaction.

Privacy by Design

Zero personal data required. No KYC. Device-bound keys never leave the device. Compliant with BACEN regulations.
